AbstractEffective diamond and mineral exploration in glaciated terrain calls for a thorough knowledge of the glacial geology of the area concerned. Over the last two decades the basis for drift prospecting in Canada has significantly improved through the continued development of ice sheets models, the acquisition of empirical evidence for ice flow, drift composition and glacial history through an improved understanding of glacial processes. Particular attention has been paid to the nature and evolution of ice sheet growth, ice divide migration and ice streaming during deglaciation. Understanding the erosional and depositional records of ice flow is critical. The type, definition, provenance and relative age of the geological record, including streamlined landforms, reflect their geographic and glaciological context in the former ice sheet, and they cannot be weighed equally for the interpretation of glacial dispersal patterns.

The intent of this lecture is to succinctly highlight processes and features specific to glacial materials derived, transported and deposited within western Canada. The message for exploration is that relations among bedrock, drift composition and ice flow history must be inferred in the wider context of the ice sheet and glacial history through recognition of the distinct character of the erosional and depositional records.
